To all whom, it may concern:

Be it known that I, JOHN PARKER, of the city and county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Vertical Spindle Attachments; and I .do hereby declare the fol- I lowing specification, taken in connection with the accompanying drawings, forming a part of the same, to be a full, clear, and exact description thereof.

The invention relates to vertical spindle attachments for horizontal milling-machines. These attachments are commonly provided with a swivel-head in which the cutter-spindle is mounted and by the adjustment of which the inclination of the spindle to the work-table may be varied. By means of this swivel-head the spindle can be adjusted in ut. a single plane, and it has been customary heretofore to provide a'second swivel in cases where it is desired to vary the adjustment partly in elevation.

In the construction shown in the drawings the spindle A is mounted in suitable bearings in a swivel-head B and is provided with the usual socket A and bolt A -for connection the shank of the cutter to the spindle. The swivel-head is mounted upon a cylindrical bearing C, formed on the support O, and is held in adjusted position by nuts B, which engage the ends of bolts the heads of which engage T-grooves C formed in the support O.

The spindle A is driven through a bevelgear D, which engages a pinion D. secured to the spindle. The gear D is arranged concentric with the axis of the swivel-head, so that the gear and pinion whatever the adjustment of the swivel-head. The ear D is formed on the end of a sleeve D Wiicll forms a hollow driving-shaft with which the spindle ofthe machine to which the attachment is secured may be connected. The sleeve D is mounted in a bushing O rigidly fixed in the support C.

The support O is provided at its upper end with an openin O Figs. L and 2, shaped to fit the end of t e center-head arm E of the machine to which the attachmentis to be secured. The upper wall of the opening C is cut throu h, as indicated at C, so that the j walls of the opening may be drawn toward each other by clamping-bolts C and th'us'the support be rigidly clamped upon the end of driven from the spindle of f'the center-head arm. When the support 0 which the attachment is sei is secured in position, it is ri idly supported cured in either of its two positions. Thisfeal and held below the driving-shaft D by 'con ture of the invention, as well as the further l nection with a bracket F. The bracket F'is features which I have employed in embody- I constructed to fit over the vertical ways El, ing this feature in a simple and efficient conon which the saddle of the milling-machineis struction, will be understood from the follow guided, and is rigidly clamped to said ways by ing detailed description. of the'attachment, l means of a clampiri bolt and nut FT.
